| dc.description.abstract | The effect of clearcutting and partial cutting on early regeneration community composition was investigated in an East Texas bottomland hardwood forest. The hypothesis tested was that species diversity would increase with harvest intensity. Tree species compositions of three structural strata (overstory, understory, and regeneration) were determined prior to and one year following harvesting. Species composition (absolute density) was ordinated in a species by sample matrix using detrended correspondence analysis (DECORANA). Displacement of treatment from pre-to postharvest position within ordination space was utilized to determine compositional change. Shannon's Diversity Index and importance values were also utilized to quantify composition. Displacement of treatment position within ordination space, fluctuations in importance values and changes in Shannon's Index values from preharvest to post-harvest indicated no significant differences in species diversity within one year of treatment in clearcuts, partial cuts, or non-cut control stands. Regeneration resilience following both partial cutting and clearcutting was strongly influenced by a dominance of Quercus spp. in the overstory and regeneration strata prior to treatment. | en |
